Seattle Seahawks wide receiver Percy Harvin will miss Sunday's NFC championship game after he was not cleared by doctors following a concussion suffered in last week's playoff game against New Orleans.

Seattle coach Pete Carroll announced Harvin's status after practice on Friday. Harvin did not participate all week and was not cleared through the league's concussion protocol. Harvin's loss subtracts a significant playmaker from Seattle's offense heading into the game against San Francisco.

"It's super disappointing for Percy," Carroll said.

Harvin suffered the concussion late in the first half while jumping for a pass in the end zone and hitting his head on the turf as he was being hit by New Orleans safety Malcolm Jenkins. It was the second big hit Harvin absorbed in the game. He was belted by Rafael Bush on Seattle's opening possession, a hit that drew a 15-yard penalty.

Harvin brought a jolt of energy and excitement to Seattle's offense before being injured. Harvin had three receptions and had a 9-yard run on his lone carry. He also drew attention and made Seattle's offense function better. The Seahawks had 163 yards of offense in the first half and 114 yards in the second half, 62 on their final possession.

"Yes, without a doubt I believe these receivers can get it done. I think we've been able to prove that throughout the season," Seattle wide receiver Doug Baldwin said. "Obviously, we would have loved to have Percy on the field not only because he's a great football player, but he's a great teammate and he's been trying so hard to get back on the field. But we have more than enough and guys that are capable of getting the job done."

Linebacker K.J. Wright will play after being out since fracturing his foot in Week 14. Wright was injured against the 49ers but worked diligently rehabilitating his foot after having surgery to insert a screw to stabilize the fracture.

Wright said he wasn't sure if he would start. Malcolm Smith has been starting while Wright was out.
